Supporting your subsea pipeline project, Cortez Subsea aim to reduce the cost of subsea pipelay in mature and shallow water regions by advancing proven technology and methods.
An alternative to the traditional welded pipeline installation, the Cortez Subsea Modular Pipelay System (MPS) partnered with the NOV Zap-Lok® pipeline connection technology is designed to provide safe, efficient and cost effective installation of subsea pipelines.
This innovative method brings together the proven technology of Zap-Lok®, a world leader for 40 years in the mechanical connection of carbon steel pipes, and our new MPS which fits onto a range of suitable dynamically positioned offshore vessel allowing the rigid pipeline to be installed.
Cortez Subsea’s MPS along with the Zap-Lok® installation press connects the pre-formed pipe’s “bell-end” and “pin-end” ranging from 4” to 12” API5L to X65, Schedule 80 line pipe. The newly joined pipe is S-laid onto the seabed at a rate of between 3km to 5km per 24hrs in water depths up to 150m.
Zap-Lok® connections have been utilised extensively throughout the oil and gas industry for many thousands of miles of flow lines, gathering lines, water lines and aided injection systems.
The MPS can be transported worldwide for local mobilisation to any suitable DP vessel, providing clients with greater vessel choice.
Combining the MPS system with efficient and effective onshore and offshore project management and engineering design analysis and installation, Cortez Subsea can provide clients with the expertise needed for successful rigid pipeline project completion.
